Abstract

The invention discloses a light through-wall imaging radar, which belongs to the technical field of through-wall imaging radar, and solves the problems of large weight and large occupied space and lowmeasurement precision of the through-wall imaging radar in the prior art. The radar comprises a motherboard, an antenna, a power amplifier, a scanning mechanism and a driver. The antenna is mounted on the power amplifier and connected to the power amplifier, and the power amplifier is connected to the motherboard. The scanning mechanism comprises a slide rail frame, a lateral scanning frame, a longitudinal scanning frame and a scanning platform. The power amplifier and the scanning frame platform are mounted on the scanning frame platform. Both ends of the horizontal scanning frame and the vertical scanning frame are slidably connected to the slide rail frame, respectively. The drive drives the scanning frame platform to move laterally along the lateral scanning frame and longitudinally along the longitudinal scanning frame. The above-mentioned light through-wall imaging radar can be used for imaging display and detection identification.

Description

technical field [0001] The invention relates to the design of a wall-penetrating imaging radar, in particular to a light-weight wall-penetrating imaging radar. Background technique [0002] Through-wall imaging radar is used for imaging display and detection and identification of concealed objects in cement walls, brick walls and other walls, and can identify electronic devices in building walls. It is widely used in security and other fields. [0003] In the prior art, in order to increase the single detection area of ​​the through-wall imaging radar, most of the through-wall imaging radars need to be equipped with two-dimensional scanning mechanisms and antennas that cooperate with each other to work. The lateral movement device and the longitudinal movement device of the two-dimensional scanning mechanism Usually stacked, for example, when the antenna moves horizontally, the antenna moves on the horizontal moving device. When the antenna moves vertically, the antenna and ...
